Didn't make it into Microsoft's Office 15 Technical Preview? Neither did we, however that has not stopped details about the next iteration of the office software suite from leaking out. CNbeta.com is flashing shots of a new red Metroized logo (no surprise) that's similar to Windows 8's err... window and showing off the name "Office 2013 Preview", while LiveSide.net has a comparison shot of the Web Apps Preview, seen above featuring a flattened look and spaced out buttons similar to screenshots seen earlier. We're still expecting a public beta of Office 15 / 2013 later this summer so it shouldn't be too long before we're all sharing the excitement of filling up cells and parsing data as though it was for the first time.

Update: Added clarification that the shot above is from the Office Web Apps preview.
